Journal Article
Talwar, R., Adachi, T., Berg, G. P. A., Bin, L., Bisterzo, S., Couder, M., deBoer, R. J., Fang, X., Fujita, H., Fujita, Y., Görres, J., Hatanaka, K., Itoh, T., Kadoya, T., Long, A., Miki, K., Patel, D., Pignatari, M., Shimbara, Y., Tamii, A., …Yosoi, M. (2016). Probing astrophysically important states in the ²⁶Mg nucleus to study neutron sources for the s process. Physical Review C, 93(5), https://doi.org/10.1103/physrevc.93.055803

Background: The ²²Ne(α,n) ²⁵Mg reaction is the dominant neutron source for the slow neutron capture process (s process) in massive stars, and contributes, together with C¹³(α,n)O¹⁶, to the production of neutrons for the s process in asymptotic giant...

Neutrons produced by the carbon fusion reaction ¹²C(¹²C,n)²³Mg play an important role in stellar nucleosynthesis. However, past studies have shown large discrepancies between experimental data and theory, leading to an uncertain cross section extrapo...

Constraining the 12C+12C fusion cross section for astrophysics (2015)
Presentation / Conference Contribution
Bucher, B., Fang, X., Tang, X., Tan, W., Almaraz-Calderon, S., Alongi, A., Ayangeakaa, A., Beard, M., Best, A., Browne, J., Cahillane, C., Couder, M., Dahlstrom, E., Davies, P., DeBoer, R., Kontos, A., Lamm, L., Long, A., Lu, W., Lyons, S., …Wiescher, M. Constraining the 12C+12C fusion cross section for astrophysics

The 12 C+ 12 C reaction is one of the single most important nuclear reactions in astrophysics. It strongly influences late evolution of massive stars as well as the dynamics of type Ia supernovae and x-ray superbursts. An accurate estimation of the c...
